Overview
The ASL2500SHNY is a two-phase automotive LED boost driver IC from NXP Semiconductors. It is an AEC-Q100 Grade 1 qualified component designed for high-reliability applications. The device operates as a DC-DC step-up regulator with two outputs and supports no dimming functionality. It utilizes a 32-HVQFN (5x5) package. The typical switching frequency is specified at 180 kHz. The operating ambient temperature range extends from -40 °C to +125 °C, ensuring robust performance in demanding automotive environments.
Feature Summary
- Two-phase architecture for efficient power delivery
- AEC-Q100 Grade 1 qualification for automotive reliability
- Integrated DC-DC step-up regulation capability
- High thermal tolerance for extreme ambient conditions
Applications
- Automotive exterior lighting systems
- LED headlamp modules
- High-power automotive illumination circuits
Procurement Notes
Verify the specific suffix 'Y' against the manufacturer's official documentation to confirm exact marking and packaging details. Ensure compatibility with the required 32-HVQFN footprint during PCB layout. Confirm that the no-dimming specification aligns with the system design requirements, as this variant does not support external dimming control signals.
Selection Notes
Select this component when a two-phase boost topology is required for automotive LED drivers. The AEC-Q100 Grade 1 rating makes it suitable for critical safety-related lighting applications. Consider the 180 kHz switching frequency for EMI management and filter size optimization. The wide operating temperature range supports deployment in harsh under-hood or exterior vehicle locations without additional derating concerns.
Part Context
This part belongs to NXP's ASL series of automotive LED lighting drivers. It complements other variants like the ASL2416SHN, which offers buck mode operation instead of boost. The series focuses on providing reliable, qualified solutions for modern automotive lighting architectures requiring precise current regulation and high efficiency.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify pin-to-pin compatibility and electrical specifications before considering alternative components from other manufacturers.
